Syphilis is a type of sexually transmitted disease caused by infection with the syphilis spirochete, which causes erythema, papules or an erythematous, scaly rash on the skin. Patients do not have itching or other conscious symptoms, and the characteristic rash can appear as a coppery-red patch on the palms of the hands and the plantar areas of the feet. The characteristic rash may appear as a coppery-red rash on the palms of the hands and feet. Most patients have had unclean sexual intercourse prior to syphilis. If you suspect that you have syphilis, you should go to the hospital to have blood tests. There are also some dermatitis and eczema that can have red spots and papules, but also no itching symptoms, which must be excluded from syphilis.
